It is an object of this invention to produce a new and improved safetycontrol valve having gravity actuated means to automatically control theflow of fluid through said valve.

It is an object of this invention to produce a new and improvedautomatically controlled valve for use on ships, planes, trailers or anymovable device or mobile body where the fluid flows by gravity orpressure and in which the fluid flow may be controlled automatically bythe action of gravity on the relatively movable parts of the valve.

It is an object of this invention to produce a new and improved valvehaving an inlet portion and an outlet portion in which a tiltableuniversally suspended valve element cooperates with the outlet portionto automatically control the outlet by the action of gravity when thevalve is tilted by the movable device in which said valve is mounted.

It is also an object of this invention to produce a new and improvedfeed control valve for tanks, carbureters, oil burners, receptacles,etc., when mounted on movable conveyances.

Other features of novelty and utility will be apparent from a detaileddescription of the accompanying drawings in which:

Figure 10 is a vertical section of the inlet portion of my device takenon the line Ifll 0 looking in the direction of the arrows shown inFigure 9.

Figure 11 is a sectional view similar to that shown in Figure 9, exceptthat the valve is tilted and the outlet portion is closed.

Figure 12 is a section on the line Iii-42 of Figure I, lookingdownwardly on the head of the valve element, showing the exit orificesin saidvalve head.

Figure 13 is a vertical section of the tubular inlet valve element usedin one embodiment of my invention.

The preferred embodiment is illustrated in Figures 1 to 5, inclusive,and comprises a valve i having a bottom section 2 and a top section 3bolted together by lag bolts or screws 4 to form a fluid tight jointbetween said sections.

The valve is provided with an inlet portion 5 in the top section 3 andan outlet portion 5 in its bottom section. Within the valve is located avalve element 1 having a weighted head 8 formed integral with a hollowstem 9. The upper portion of the stem 9 is provided with a spherical endportion l0 secured by a ring H to the upper portion of the valve. Thering H is fastened to the top section 3 by lag bolts or screws l2, saidring and top section forming a socket. The valve element 1 is mountedfor limited swinging pendulum-like movement in any arcuate directionfrom its central axis as clearly disclosed in Figure 5. v

The lower section 2 is provided with a valve seat or face portion l3defining a spherical surface portion subtended by a radius extendingfrom the center of the spherical end portion Ill. The element 1 isprovided on its head 3 with a complemental spherical valve face Itcooperatively related to the face I 3. The clearance between these valvefaces [3 and is need not exceed .003 of an inch.

It will be noted that the valve element 1 is weighted and gravityactuated to control both the inlet and outlet of the valve I. Of course,to get'this desired automatic gravity control of flow to and from thevalve I, the valve is secured in fixed position on or in mobile body ormovable device such as an airplane, a dirigible balloon. ship,automobile, trailer, etc.

It will be seen that this valve construction is well adapted as a feedcontrol valve for carburetors, oil burners, tanks, receptacles, etc.when mounted on movable conveyances. l

The embodiment of my invention as disclosed in Figures 6 to 13,inclusive, is similar to the embodiment disclosed in Figures 1 to 5,inclusive, in that the pendulum valve element l1 bears the samefunctional relation to the valve casing section I9 as that previouslydescribed.

In this embodiment the valve 18 comprises a bottom section IS, a topsection 23, a valve element I! controlling an outlet portion 2| and afloat contrelledrinlettportiont43ihaving. a cut-offvaive22"having aninlet end-'22 and 'an outlet orifice 23. This cut-oi? valve 22 isslidably fitted in a bore 24 of the lower or bottom section of the valvecasing.

When the outlet portion is closed by the tilting of the valve 18 and theswinging or oscillation of the pendulum valve element H, the incomingliquid, because of greater specific gravity than the float structure 26,forces the float 26 upwardly which carries with it the cut-off valveelement 22, thereby cutting off or at least retardghollow m'zsingi' thesupply 'of liquidf fIt-is to be noted that move in the same direction asthe flow of liquid; J therefore, both the float 26 and the valve element.22- areactuatedrby the force of gravity.
